Calm waves and clear skies.
Wind speeds and wave heights were cut in half on Monday compared to the previous day as a high pressure front moved into the area.
Weather conditions have finally turned favorable for search-and-rescue crews in waters off Jin-do island, and the clear weather is forecast to continue through this Friday.
Strong tidal currents, which significantly hampered the rescue operations last week, have also slowed.

"Last week was the time when the current speeds were the fastest, and from the 19th,.. it has been slowing down. Starting this Tuesday, the speeds will be at their slowest."

Last week, the maximum speed of the currents in the area were 2.8 meters per second, or over 10 kilometers per hour.
That is expected to drop as low as about one meter per second, especially from this Tuesday to Thursday.
When tidal currents slow, underwater visibility improves, with less floating particles in the sea.
That's why experts believe this week will be a turning point in search operations inside the sunken Sewol-ho ferry.
